Feed Water Connections

1. Locate the length of 3/8" (0.95 cm) O.D. tubing provided with a quick disconnect insert on one
end and a 3/8" O.D. X 1/4" NPT tubing adapter on the other.
2. Install the tubing adapter onto your incoming water line (Figure 3-17). We recommend a
customer supplied shut off valve be installed in your feed water line.
3. The quick disconnect end of the tubing will be inserted into the feed water inlet on the lower left
corner in the rear of the Thermo Scientific TII (Figure 3-17).

The RO reject and flush water is sent to drain through this connection.
1. Locate the drain water tubing. This is the 1/4" (0.64 cm) O.D. tubing that is approximately 6 ft.
(1.83 m) long with a 1/4" O.D. x 1/4" N.P.T. tubing adapter on one end. The atmospheric drain
fitting is located on the lower left corner in the rear of the Thermo Scientific TII.
2. Install the tubing adapter into an atmospherically vented drain and route the tubing to the
Thermo Scientific TII drain connector, ensuring that there are no kinks.
